  - Store the device_t of the smbX device in the softc.
  - Store the softc of the device in the 'si_drv1' of the cdev.
  - Lookup the softc via 'si_drv1' in cdev methods rather than using the
    minor number as a unit for devclass_get_softc().
  - Lookup the device_t via the softc field in cdev methods rather than
    using the minor number as a unit for devclass_get_device().
  - Add a mutex to the softc to protect 'sc_opened'.
  - Remove D_NEEDGIANT as all the smbus drivers are now MPSAFE and this driver
    is now MPSAFE.
  - Remove some checks for NULL softc pointers that can't happen and don't
    bzero the softc during attach.
